To all whom t may concern:

Be it known that I, ROBERT tNELsoN FRAME, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Bookmarkers, of which the following is a specification.

This invention relates to a movable marker or indicator designed more particularl for use on the leaves of account books to acilitate reference to entries and guard against oversights, especially where the work of the bookkeeper or auditor is liable to interruptions.

The object of my invention is the provision of a convenient and inexpensive device of this character which can be readily shifted from line to line of an account or from place to place of a page, and which at the-same time is attached with sufficient security to prevent its accidental displacement;

In the accompanying drawings:

Figure 1 is a face view of the marker applied to the leaf of a led er. Fig. 2 is a etached from the book. Fig. 3 is a longitudinal central section of the marker. F1g. 4. is a side or edge view thereof applied toa leaf .which is shown in section.

Similar characters of reference indicate'y corresponding parts throughout the several views.

The marker or indicator consists of a plate 1, preferably of thin sheet metal, as spring steel, having the form of an arrow with a comparatively broad tail, as shown. This late is of the properl len th to extend rom the outer, side edges o the bookleaves to the amount-columns or to any other desired point.

The plate is adapted to lie flat upon the face of a leaf and is provided with a spring tongue 2 adapted to bear against the back of the same or another leaf, as shown in Fi 4, so as to clasp the marker to the lea or leaves. This tongue is arranged lengthwise of the marker and extends inwardly from a point near its outer end, the same being of suitable length to form an extensive holding surface. As shown, the tongue is stamped integral with the body of the marker by cutting a three-sided opening-3 of proper form therein. Through this opening the entries in the underlying columns are displayed.

. In the preferred embodiment of the device I plate. This construction permits the tongue to receive and embrace either one or several leaves and et allow it and the plate to bear substantial y flat against the leaves. The free end of the tongue may be curved away from the plate, as shown at 5, to form a flaring mouth between these parts which facilitates the application of the marker to the leaves.

If desired, the marker may be provided with an opening 6 for suspending it from a hook or other support.

In the use of the device, the same is simply slipped over the' ed e of the leaf to be marked, with its shou der-4 abutting against the edge of the leaf, and as the work progresses,the marker is shifted over the page,A

its projecting tail affording a convenient han le for this purpose.

Both the face or indicator plate 1 and the tongue 2 are fiat and smooth and free from projections of any kind and the de vice is therefore not liable to wrinkle the leaves `of a book, or tear them in applying and removing it.

While the improvement is herein shown in connection with an account book it is equally serviceable for other bookso yvarious kinds, such for exam le, as stenog plate with an offset arran ed on the reary side of the plate, whereby t e tongue is depressed rearwardlyout of the plane of the plate, all portions ofsaid plate being fiat, smooth and free from projections and lying in the same Blaue excpt said ton e.
